3M 2516-6002UG Equivalent & Substitute Parts

Part Overview

The 3M 2516-6002UG is a rectangular connector header designed for through-hole mounting applications. This 16-position, 2-row connector with 0.100" (2.54mm) pitch and shrouded 4-wall design is classified as obsolete. Due to its discontinued status, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements. Suitable alternatives maintain the core electrical and mechanical specifications while offering improved compliance and availability.

Engineering Selection Recommendations

Primary Recommendation: N2516-6002-RB (3M)

The N2516-6002-RB is the direct active-product successor to the 2516-6002UG. It maintains identical mechanical and electrical specifications while offering ROHS3 compliance and improved contact finish durability (30.0µin gold vs. 15.0µin). Post finish is upgraded from Tin-Lead to Tin. This part is the preferred choice for direct replacement in new designs and production transitions.

Secondary Recommendation: D2516-6002-AR (3M)

The D2516-6002-AR provides full RoHS compliance and maintains the same operating temperature range and current rating. It differs in contact material (brass vs. copper alloy) and insulation height (0.253" vs. 0.390"), making it suitable for applications where these variations are acceptable. Tray packaging supports higher-volume production.

Alternative Options: Molex C-Grid Series (0702461601, 0702461602, 0702461604, 0878341611, 0878341641)

Molex connectors offer ROHS3 compliance and high inventory availability. The C-Grid 70246 series (0702461601, 0702461602, 0702461604) uses phosphor bronze contacts and PBT insulation. The C-Grid 87834 series (0878341611, 0878341641) uses copper alloy contacts with nylon insulation. These parts are suitable for applications where manufacturer diversity is required or where specific packaging formats (bulk vs. tray) are mandated.

Alternative Option: KYOCERA AVX 008383016000010

The KYOCERA AVX part offers ROHS3 compliance and active product status. It features brass contacts and nylon insulation. Current rating is specified at 1A (vs. 1.75A for the main part), which may limit suitability for higher-current applications.

Alternative Option: TE Connectivity AMP-Latch Series (103309-3, 5103308-3)

TE Connectivity parts maintain the -65°C to 105°C operating range and offer active product status. The 5103308-3 provides RoHS compliance with Tin post finish. The 103309-3 retains Tin-Lead finish and RoHS non-compliance status. Current rating is specified at 1A per contact (vs. 1.75A for the main part).

Frequently Asked Questions (FAQ)

Q: Can the N2516-6002-RB directly replace the 2516-6002UG without PCB redesign?

A: Yes. The N2516-6002-RB maintains identical pitch (0.100"), position count (16), row configuration (2 rows), shrouding (4-wall), and mounting type (through-hole). No PCB footprint modification is required.

Q: What is the primary difference between N2516-6002-RB and D2516-6002-AR?

A: The N2516-6002-RB uses copper alloy contacts with insulation height of 0.390", while the D2516-6002-AR uses brass contacts with insulation height of 0.253". Both maintain the same pitch, position count, and operating temperature range. The D2516-6002-AR is optimized for board-to-cable/wire applications, whereas the N2516-6002-RB supports board-to-board or cable configurations.

Q: Are Molex connectors mechanically compatible with 3M connectors?

A: Molex C-Grid 70246 and C-Grid 87834 series maintain the same 0.100" pitch, 16-position, 2-row configuration, and shrouded 4-wall design. Mechanical compatibility is confirmed for mating with standard 0.100" pitch receptacles. Contact material and insulation composition differ, which may affect electrical performance in specific applications.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness (measured in microinches or micrometers) affects durability and wear resistance. The original 2516-6002UG specifies 15.0µin (0.38µm) gold mating finish. Substitute parts range from 5.00µin to 30.0µin. Higher thickness generally provides improved corrosion resistance and contact longevity, particularly in high-cycle mating environments.

Q: Why do some substitute parts list operating temperature as "-" instead of a specific range?

A: Operating temperature specifications are provided only when explicitly documented by the manufacturer. Absence of this specification does not indicate unsuitability for the -55°C to 105°C range; it reflects incomplete technical documentation in the source data. Consult manufacturer datasheets for complete thermal specifications.

Q: What is the difference between RoHS non-compliant, RoHS Compliant, and ROHS3 Compliant status?

A: RoHS non-compliant parts may contain restricted substances (lead, cadmium, hexavalent chromium, etc.). RoHS Compliant parts meet the original RoHS Directive requirements. ROHS3 Compliant parts meet the updated RoHS 3 Directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. For new designs, ROHS3 Compliant parts are preferred.

Q: Can the TE Connectivity 103309-3 be used in applications requiring 1.75A current rating?

A: The 103309-3 specifies 1A per contact current rating, which is lower than the original 2516-6002UG specification of 1.75A. Use of this part in applications requiring 1.75A per contact is not supported by the provided specifications.

Q: What packaging options are available for high-volume production?

A: Bulk packaging is available for Molex 0702461601 (9163 Pcs inventory) and Molex 0878341611 (1840 Pcs inventory). Tray packaging is available for multiple suppliers, with Molex 0702461602 offering the highest inventory (13705 Pcs). Tube packaging is available for TE Connectivity 103309-3 (1246 Pcs).

Q: Are there any compliance or certification differences that affect part selection?

A: The original 2516-6002UG is RoHS non-compliant and REACH Affected. All active substitute parts listed are ROHS3 Compliant and REACH Unaffected, making them suitable for applications subject to EU environmental regulations. ECCN classification (EAR99) and HTSUS code (8536.69.4040) are consistent across all parts.
